Patentedfict. 315, 3191189 To all whom it may concern:

Be it known that I, ALFRED HARB, a subject of the Emperor of Austria, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Toy Flying-Machines, of which the following is a spec1fication.

This invention relates to flying toys, and the main object of the same is the provision, as an article of manufacture, of a simply constructed, inexpensive flying toy adapted to be held in the hand, the same being so constructed and provided with supporting planes and a motor operated propeller that when the toy is given a quick thrust into the air, it will travel through the air for a considerable distance or until the motor is run down.

The invention resides in the details of construction and in the arrangement and combination of parts hereinafter described and shown in the accompanying drawings, forming a part of this specification, and in which Figure 1 is a top plan view of a toy made in accordance with my invention.

Fig. 2 is a view in side elevation of the to fig. 3 is a view in front elevation of the to With more particular reference to the accompanying drawings, the frame for the toy consists of a single thin longitudinal member 5', made preferably of wood and in square form.

Rigidly secured upon this frame element 5, with its longitudinal center a little forward of the longitudinal center of the said element, is a plane element 6, mad preferably of substantially air-proof paper, and formed with its opposite sides 7 and 8 converging gradually on each side of the frame element 5 and terminating in the rounded ends 9. To this plane is secured by glue or otherwise, preferably upon the top surface thereof, in order to make it approximately rigid in the peculiar form desired, the longi tudinal parallel strips 10 and 11, which are bowed at 12 over the frame element 5, and again bowed upwardly as at 13 on each side beyond the frame element 5, terminating in the downwardly curved ends 9. These longitudinal strips 10 and 11 are made preferably of leather, although they may be made of a very light wood or other suitable material with good results. Bracing these strips near their outer ends; upon the 11I1d81'- neath side of the plane (3, are the cross pieces 14 and 15. The strips 10 and 11 are also preferably secured to the frame element 5 by light'pins as 16 or other suitable means.

Secured upon the top of the rear end of the frame element 5 'isfljattriangular shaped plane 17, which is formedwith a tail piece 18, rearward] y projecting/beyond the end of the frame element 5. Upon. this plane 17 at its rear straight end is :p 'eferably secured a cross-piece 19 which is, so pinned to the frame element 5, the purpbse of the crosspiece 19 being to render comparatively rigid the rear end of this plane. Glued upon the triangular plane 17 and secured by pins as 16 to the frame element 5 in parallelism with the latter, is a vertical fin 20 designed to give stability to the toy in flying. The triangular plane 17, as well as the tin 20, is also made preferably of substantially airproof paper.

Riveted or otherwise secured to the forward end of the frame element 5, underneath the same, is a bearing member 21, of the same width as the frame element 5, and through which longitudinally is provided a bore 22, in which is arranged for rotation a spindle 23, the rear of which is formed preferably with an integral hook 2i, and upon the front end of which is rigidly mounted the propeller In order to operate the propeller, I prefer to use a substantially square longitudinal elastic motor 26, the forward end of which is engagedupon the hook 2 and the rear end of which is made fast with the frame element 5 by means of a spring clip 27, removably engaged inthe aperture 28 provided transversely through the frame element 5. VVhiIe Iprefer to employ an elastic motor element as 26, which is adapted, in view of the manner in which it is secured, to be twisted upon itself in order to operate the propeller 25, itwill'be obvious that a suitable spring motor may also be employed without changing the construction.

In operation, the-propeller 25 is rotated, twisting the elastic motor tautly upon itself. The propeller is then held rigid with the frame element- 5 until the device, by grasping the frame element 5 between the thumb and forefinger, is given a thrust through the air, preferably an upward direction, the propeller being-released simultaneously with the thrust. Having thus started the toy in flight,.the unwinding of the elastic motor will rotate the propeller rapidly, causing the device to soar in the air, for a considerable distance until the elastic motor has run down.

Having thus described my invention, what I claim is e 1. As an article of manufacture, a flying 'toy includingin combination a longitudinal frame strip provided with an underneath head at one end, a spindle mounted for rotation in said head, a propeller device fast with said spindle in advance of said head, a plane element mounted transversely upon said frame element at the rear of said head end, said plane element being bowed upwardly beyond said frame element at each side thereof, a triangular plane element mounted upon the rear end of said frame element, and motor meanssupported' under neath the frame element and connected to the propeller spindle for the operation of the propeller.

2. As an article of manufacture, a flying toy including in combination a single longitudinal frame strip provided with an underfiopiesl of this patent may he obtained for five cents each, by addressing the fiommis'sioner of ".iatents,

menses neath projecting head at one end, a spindle mounted for rotation in said head longitudinally thereof, said spindle terminating at its rear end in an integral hook, a propeller device fast with said spindle in advance of said head, a main plane mounted transversely upon said frame element at the rear of said head end, said plane being bowed partially around said frame element and also being bowed upwardly beyond said frame element at each side thereof terminating in rounded ends, the sides of said plane converging from said plane element to said rounded ends, means. for reinforcing said plane, a triangular plane mounted upon the rear end of said frame element and provided with a tail piece projecting rearwardly beyond said frame element, a fin rising from 'said triangular plane in parallelismavith said frame element and windable motor means supported underneath the frame ele men-t longitudinally thereof and connected to the hooked end of the propeller spindle K Washington, W.
